From skimming I basically agree on the responses. Just two things.
DP- Accounting for Legends, TPM Maul would still have a power edge over Obi-Wan. Levitating a "huge boulder" without even having to look or gesture, and nearly Force screaming a barracks to the ground at the age of 15, coincides nicely with the level of power we saw from him during TCW. TCW Maul is likely more powerful, but not by a huge degree IMO. While he did have a lot of time to brood in isolation and gain power by doing so, he also lost half of his potential, which would curb him to some degree as well. TPM Maul's usage of TK and the like is just more subtle or restrained.
